Improving Employee Productivity through LinkedIn Networking: A Study of Banks in Rivers State University, Port Harcourt, Nigeria

Social networking is rapidly changing the way employees interact with customers and the organization as a whole; and one form of social networking is LinkedIn networking. This study examined the relationship between LinkedIn networking and employee productivity measured in terms of service quality and employee task accomplishment of banks operating in Rivers State University, Port Harcourt, Nigeria. A survey design was adopted for the study using questionnaire as the research instrument. The population of this research work was made up of 77 employees of the money deposit banks in focus; all of who were administered copies of the questionnaire. With a response rate of about 84%, the returned and useable copies came from 65 employees. Frequencies and mean scores were used for the presentation of data; and the Spearman’s rank correlation coefficient and regression analysis were used to test the relationship between the LinkedIn networking with each of the two measures of employee productivity used in this study and strength of explanation (co-efficient of determination). The Statistical Package for Social Sciences (SPSS) Windows version 22 with a criterion significance level of 0.05 was employed. The findings revealed that LinkedIn networking has significant influence on service quality and employee task accomplishment. It was, therefore, recommended that employees of the banks should use LinkedIn as a constructive and effective means for enhancing their productivity in terms of service quality and task accomplishment.

Analysis of traffic engineering and fast reroute on multiprotocol label switching

Multiprotocol Label Switching (MPLS) is a technology developed to address the bottleneck of Internet Protocol over Asynchronous Transfer Mode network. It is a packet forwarding technology using labels to make data forwarding decisions. The use of label forwarding instead of IP address consumed a lot less resources in the old days as it was faster but nowadays the speed improvement is negligible due to new lookup table algorithm. However, it is one of the most utilized technologies among Internet Service Providers due to its Traffic Engineering (TE) capability. In this research, a deductive methodology has been used to evaluate the benefit of MPLS Traffic Engineering in the presence of traffic collision and we investigate how the implementation of Fast Reroute (FRR) helps to reduce the convergence time in case of link/node failure. Results show that TE helps to improve the quality of service in terms of latency in the presence of background traffic and FRR helps to reduce convergence time to less than 100 ms.

Resource Allocation in f-OFDM Wireless Networks with Delay Estimation Using Service Curve and Envelope Process

In this paper, a resource allocation algorithm for wireless communication systems is proposed, which considers the channel transmission quality and data delay. In the proposed approach, the delay value is estimated to decide on the allocation of available radio resources, aiming to reduce the system’s average delay. For the delay estimation, an approach involving concepts of Network Calculus such as service curve and envelope process MFBAP (Multifractal Bounded Arrival Process) is proposed. In view of the recent techniques for 5G communication systems, f-OFDM (filtered-Orthogonal Frequency Division Multiplexing) technology is also considered in our simulation scenarios. Simulations are carried out to compare the performance of the resource allocation algorithms in terms of QoS (Quality of Service) parameters such as average delay, throughput, processing time, loss rate and fairness index, proving the efficiency of the proposed algorithm.

ADVANCED TENSOR APPROACH TO FAST REROUTE WITH QUALITY OF SERVICE PROTECTION UNDER MULTIPLE PARAMETERS

Conclusions. Implementation of an improved tensor approach to solving the problem of fast rerouting will ensure the fault tolerance of the infocommunication network with the protection of the level of quality of service in terms of bandwidth, average end-to-end delay, and the probability of packet loss.

Impact of Service Quality Dimension on Customer Satisfaction of Domestic Electricity Consumers in Sri Lanka

Electricity is becoming an essential part of life considering the increasing needs and wants of human beings. In Sri Lanka, Electricity is widely used for domestic purposes by Domestic Consumers. Customers are always expected to get the new connections within a short period of time, un-interrupted service at any time, affordable tariff system, easy payment facilities and customer-oriented attitudes of employees etc. Evidences do not prove that Ceylon Electricity Board (CEB) has been able to meet the above customer expectations fully. The problem was the gap between expected service and perceived service delivered to domestic electricity consumers by CEB. In some extent CEB is lacking behind of understanding about the customer expectations and thereby encountering difficulties in transforming customer expectations in to superior service quality specifications that employees can understand and execute. This study is an effort to come up with the solution to the major research problem that was identified by the authors as service quality identification through customer satisfaction. Current study desires to develop an empirical model of service quality in terms of electricity services that may form a basis for a better understanding of its determinants. Specifically, this study aims to identify the dimensions of service quality of electricity services provided by the Ceylon Electricity Board in North Western Province. Accordingly, scope of the present research is confined to service marketing concept: customer satisfaction. Customers are not only buying the product or arriving at the organization but including industry owners outside agencies, other outside personnel who are beneficiaries in the service offered by CEB. This study is based on the domestic electricity consumers in North Western Province in Sri Lanka. The North western province is divided in to seven areas. These seven areas are subdivided into twenty five consumer service centers. There were 863,581 consumers at the end of 2016.Using Johnson & Kuby (2007) simple sampling technique, sample size was found as 300. Therefore, 300 respondents were selected for 25 consumer service centers proportionate to the population of each consumer service center. Data were collected using a questionnaire, from 300 respondents. Customer satisfaction is measured with service quality dimensions of tangibility, empathy, responsiveness, reliability, assurance. Correlation analysis and multiple regression analysis were used to analyze the data. The model framework developed based on the SERVQUAL model invented by Parasuraman, Zeithamal and Berry (1988). The results showed that tangibility, empathy, responsiveness, reliability and assurance had significant positive relationships on customer satisfaction. Based on the findings some suggestions for electricity utility were discussed. Findings will be useful to CEB for enhancing its effectiveness and to build up the high level of customer satisfaction. Moreover, findings of the study enrich the empirical literature and provide important messages for the policy makers and enlightening substantial scope for future research.

Assessing the market niche of Eurasian rail freight in the belt and road era

PurposeThis paper presents an overview of the recent development of Eurasian rail freight in the Belt and Road era and further evaluates its service quality in terms of transit times and transport costs compared to other transport modes in containerised supply chains between Europe and China.Design/methodology/approachA trade-off model of transit time and transport costs based on quantitative data from primary and secondary sources is developed to demonstrate the market niche for Eurasian rail freight vis-a-vis the more established modes of transport of sea, air and sea/air. In a scenario analysis, further cargo attributes influencing modal choice are employed to show for which cargo type Eurasian rail freight service is favourable from a shipper's point of view.FindingsAt present, Eurasian rail freight is about 80% less expensive than air freight with only half of the transit time of conventional sea freight. Our scenario analysis further suggests that for shipping time-sensitive goods with lower cargo value ranging from $US1.23/kg to $US10.89/kg as well as goods with lower time sensitivity and higher value in a range of $US2.46/kg to $US21.78/kg, total logistics costs of Eurasian rail freight service rail is cheaper than all other modes of transport.Practical implicationsAs an emerging competitive solution, Eurasian rail freight demonstrates to be an option beneficial in terms of transport cost, transit time, reliability and service availability, which offers a cost-efficient option enabling shippers to build up agile and more sustainable supply chains between China and Europe.Originality/valueOur study firstly provides a comprehensive assessment of present Eurasian rail freight including a thorough comparison with alternative modes of transport from a shipper's point of view.

ОПТИМІЗАЦІЙНА МОДЕЛЬ МАРШРУТИЗАЦІЇ ЧУТЛИВОГО ДО ЗАТРИМОК ТРАФІКА В ІНФОКОМУНІКАЦІЙНИХ МЕРЕЖАХ

У роботі запропоновано вдосконалену оптимізаційну модель маршрутизації чутливого до затримок трафіка в інфокомунікаційних мережах. Новизною моделі є використання критерію оптимальності, що пов'язаний з мінімізацію середньої міжкінцевої затримки пакетів. В основу зазначеного критерію оптимальності покладено математичний вираз, який дозволяє аналітично розрахувати середню міжкінцеву затримку з урахуванням характеристик мережного трафіка, типів дисциплін обслуговування пакетів на маршрутизаторах інфокомунікаційної мережі, пропускних здатностей каналів зв’язку. Також отримано умови забезпечення якості обслуговування за середньою міжкінцевою затримкою пакетів для будь-якого виду трафіка в умовах реалізації як одношляхової, так і багатошляхової маршрутизації. Отримати зазначені результати вдалося на підставі тензорного моделювання інфокомунікаційної мережі, коли тензори основних QoS-показників та метричні тензори розглядались у двох системах координат: гілок мережі та незалежних міжполюсних шляхів і внутрішніх вузлових пар. Дослідження та порівняльний аналіз з іншими маршрутними рішеннями підтвердили більш високу ефективність удосконаленої моделі за показником середньої міжкінцевої затримки пакетів, що є важливим для чутливого до затримок трафіка, особливо в умовах високих навантажень на інфокомунікаційну мережу

Joint Scheduling and Power Allocation Using Non-Orthogonal Multiple Access in Multi-Cell Beamforming Networks

The proliferation of smart devices has boosted the improvement of wireless network technologies. Herein, networking functions should be properly guaranteed even in highly dense environments in terms of service quality and data rate. In this paper, we present an efficient power allocation algorithm using non-orthogonal multiple access and smart array antennas to increase the capacity in highly overlapped multi-cell environments. We evaluate the proposed algorithm and compare with the conventional orthogonal multiple access scheme with smart antennas. Through intensive simulations and experiments at the system level for performance evaluations, it is confirmed that the proposed scheme obtains a drastic throughput gain up to 50% in the overlapped region of highly dense networks.

Evaluasi Kinerja Protokol Perutean AODV dan SDGR+R pada VANET dengan Studi Kasus Pelabuhan Lembar

The Vehicular ad-hoc Network (VANET) is a subclass of Mobile ad-hoc networks (MANETs).VANET is a wireless network created from the concept of building a vehicle network (node) toexchange data information (data communication). There is a new concept technique forVANET communication used, namely the use of the concept of Software Defined Network(SDN) on VANET. For data communication between vehicles, a routing protocol required. Themost common routing protocol used on VANET since 2003 is AODV. In 2014 several studieswere using the SDN paradigm tried on VANET technology to improve the performance ofQuality of Service (QoS), one of which is a Geographic-based SDN, called SDGR in 2016.Multicast is a method of routing data on a network that allows one node or a group of nodes tocommunicate efficiently with the receiving node. The multicast concept supports one-to-manyrouting in nodes that send packet data to a group of nodes. The development of the SDGRrouting protocol using the idea of multicast technique to SDGR based on the Direction calledSDGR + R carried out in 2019. This study uses a case study of vehicle transportationsimulations in the Lamber Port area of Lombok. The simulation results knew that SDGR + Ris better than AODV in terms of service quality (QoS) at a latency of 15.58% and packet deliveryratio (PDR) of 47.78%.

Auto-Scale Resource Provisioning In IaaS Clouds

AbstractUsers of cloud computing technology can lease resources instead of spending an excessive charge for their ownership. For service delivery in the infrastructure-as-a-service model of the cloud computing paradigm, virtual machines (VMs) are created by the hypervisor. This software is installed on a bare-metal server, called the host, and acted as a broker between the hardware of the host and its VMs. The host is responsible for the allocation of required resources, such as CPU, RAM and network bandwidth, for VMs. Therefore, allocating resources to a VM is equivalent to finding the location of the VM on the hosts. In this paper, we propose a model for resource allocation of a datacenter that includes clusters of hosts. This model is based on the birth–death process of queueing systems and continuous-time Markov chains. We will focus on RAM-intensive VMs and consider the allocation of RAM for a VM as a job in the queueing systems. The purpose of this modeling is to keep the number of running hosts minimum while guaranteeing the quality of service in terms of response. When the utilization of active hosts reaches a predefined threshold value, a new host is added to prevent response time violation, and when host utilization is reduced to a certain threshold, one of the hosts can be deactivated. The experimental results show that, in the long run, the odds of working with more jobs are increased.

Moral Sensitivity of Interns and Affecting Factors

Background: Moral sensitivity is thought to be the first step in real-life moral decision-making. In the field of health, which is seen as an ethically loaded practice, monitoring the ethical sensitivity of service providers is essential both in terms of service quality and ethical practice. This study aimed to determine the moral sensitivity and the factors that may be related to the moral sensitivity of interns.Methods: A total of 116 intern doctors who accepted to participate were included in the study without using a sampling method. In order to collect the data, a data collection form consisting of sociodemographic characteristics of the interns and Moral Sensitivity Questionaire (MSQ) was used. As the scores obtained from the scale showed normal distribution, Student's t-test was used for the comparison of two groups, and the ANOVA test was used for the comparison of three groups.Results: The mean MSQ total score of the volunteers participating in the study was 89.14. The moral sensitivity level was higher in women in total score, benevolence, and orientation subscale scores (p <0.05). According to the total score, autonomy, meaning, rules, and orientation subscale scores, the moral sensitivity levels of individuals with high-income perception were higher (p <0.05).Conclusion: The findings show that the interns’ moral sensitivity level is high-intermediate when the average Moral Sensitivity Questionaire scores are taken into consideration. The female gender and the perception of the high-income level positively affects the moral sensitivity of interns. Follow-up studies and qualitative research can be planned to clarify the reasons for this effect.

Key determinants and heterogeneous frailties in passenger loyalty toward customized buses: An empirical investigation of the subscription termination hazard of users

Long-term passenger subscription is vital to the survival and operation of the customized bus (CB) system, which is a demand-driven and user-oriented transit service. A better understanding of passenger loyalty toward the CB service will help provide better operation. The urgent and outstanding issue is how to incorporate the unobserved heterogeneity in loyalty—in other words, how to reflect the effects of the frailty to terminate subscription. This study fills the research gap through an empirical study in Dalian, China. Three different survival models are developed to investigate the mechanism of subscription behaviors, among which the shared frailty model considering the unobserved heterogeneity is demonstrated to be the most appropriate. The results indicate that the historical purchase characteristics are the most important to CB user loyalty modeling and forecasting. Males are more sensitive than females to the number of intermediate stations because of the potentially increased uncertainty in waiting time related to the intermediate stations. The heterogenous frailties resulting from the heterogeneity of the perceptible service quality in terms of convenience and efficiency in subscribing/returning tickets and information availability in the progress of the CB system significantly contribute to user loyalty deviations.

The study of public perceptions on the quality service of Trans Mebidang Bus

Transportation is a pivotal thing that supports everyday human life and the movement of logistics goods. The transportation system is said to be good if the cost is economical and affordable. However, it seems that the city of Medan has not been implemented, costs are only determined by the government and public transport organizations without involving the community. The low quality of services in terms of safety, comfort, feasibility, ease and efficiency of public transport, provide a feeling that is less comfortable and safe for users of public transport services. The increasing number of people using private vehicles in the city of Medan increases traffic congestion which results in longer travel times, due to many vehicles and lower speeds. The point is that private vehicle users cause congestion, inefficiency in the use of road space, and reduce road capacity. To reduce congestion in the city of Medan, the Medan city government held collaboration with Deli Serdang Regency and Binjai City; Trans Mebidang Bus was established to overcome the bottleneck. Therefore, the researchers are keen to find out the quality service of the bus through the public perception.
